About this map

The Colorado River defines the border between California and Arizona in this riverine landscape, where the shifting waters have carved a series of distinct backwaters and basins. To the west, in Imperial County, Paymaster Landing and Cibola Valley sit amidst a complex network of wetlands and drainage features including Vinagre Wash and Turnaround Wash. This riparian corridor is marked by notable desert hydrology, from the intricate Three Finger Lakes near the northern boundary to Walker Lake and Draper Lake further south along the river's path.

Remote infrastructure and landforms punctuate the desert terrain, including the Walter's Camp Airport and the prominent Lighthouse Rock overlooking the river. To the east, the Trigo Mountains rise sharply in Arizona, while more level land can be found in Paradise Valley. The presence of Arrowweed Spring highlights the critical water sources that have long dictated movement and settlement in this arid borderland between the two states.
